Abstract

Abstract Prone position though is commonly used for better access to surgical site, but may be associated with a variety of complications. Perioperative Visual Disturbances or loss is rare but a devastating complication that is primarily associated with spine surgeries in prone position. In this case we report a 42 year old ASA-II patient who developed anisocoria with left pupillary dilatation following lumbar microdiscectomy in prone position. Following further evaluation of the patient, segmental pupillary palsy of the left pupillary muscles was found to be the possible cause of anisocoria. Anisocoria partially improved but persisted till follow up.

Resumo

Resumo O posicionamento em decúbito ventral, embora comumente usado para melhorar o acesso ao local cirúrgico, pode estar associado a uma variedade de complicações. Distúrbios ou perda visual no Perioperatório é uma complicação rara, mas devastadora, que está principalmente associada à cirurgia de coluna vertebral em decúbito ventral. Relatamos aqui o caso de um paciente de 42 anos de idade, ASA - II, que desenvolveu anisocoria com dilatação pupilar esquerda após microdiscetomia lombar em decúbito ventral. Após uma avaliação adicional do paciente, observamos que a paralisia segmentar dos músculos pupilares esquerdos seria a possível causa de anisocoria. A anisocoria melhorou parcialmente, mas persistiu até o acompanhamento.
